Radial Column Chart
Also known as a Circular Column Graph or Star Graph.
This type of graph plots bars on a polar coordinate system. Concentric circles are used for the value scale, while the radial dividers (lines spanning from the centre) are used to plot each category.
Typically, the lower values on the scale start from the centre and increase with each circle outwards. The bars are plotted extending outwards from the centre based on this concentric circle value scale.
Negative values can also be displayed on a Radial Column Chart, by having zero starting from any of the outer circles (from the central one) and all circles within it used for negative values.
